Disclosure date: 2021-06-13
Last modification time: 2021-09-14 11:36:28 +0000
Supported architecture(s): x86, x64
Supported platform(s): Linux
Target service / protocol: http, https
Target network port(s): 80, 443, 3000, 8000, 8008, 8080, 8443, 8880, 8888
List of CVEs: CVE-2021-32682
elFinder versions below 2.1.59 are vulnerable to a command
injection vulnerability via its archive functionality. When
creating a new zip archive, the name
parameter is
sanitized with the escapeshellarg()
php function and then
passed to the zip
utility. Despite the sanitization,
supplying the -TmTT
argument as part of the name
parameter is still permitted and enables the execution of
arbitrary commands as the www-data
user.
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Reliability:
- repeatable-session: The module is expected to get a shell every time it runs.
Stability:
- crash-safe: Module should not crash the service.
Side Effects:
- ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.

Knowledge Base
Vulnerable Application
elFinder versions below 2.1.59 are vulnerable to a command injection vulnerability via its archive functionality.
When creating a new zip archive, the name
parameter is sanitized
with the escapeshellarg()
php function and then passed to the
zip
utility. Despite the sanitization, supplying the -TmTT
argument as part of the name
parameter is still permitted and
enables the execution of arbitrary commands as the www-data
user.
Tested on elFinder versions 2.1.57
, 2.1.58
, and 2.1.59
.
Installation Steps
- Set up a php server
- Download a vulnerable version of the elFinder software
- Rename the minimal connector file:
mv /php/connector.minimal.php-dist /php/connector.minimal.php
- Access the software at
http://<host>/elfinder.html
Additional installation methods can be found here.
Verification Steps
- Install the application
- Start msfconsole
- Do:
use exploit/linux/http/elfinder_archive_cmd_injection
- Do:
set RHOST <ip>

Payload information:
Description:
elFinder versions below 2.1.59 are vulnerable to a command injection
vulnerability via its archive functionality. When creating a new zip
archive, the `name` parameter is sanitized with the
`escapeshellarg()` php function and then passed to the `zip`
utility. Despite the sanitization, supplying the `-TmTT` argument as
part of the `name` parameter is still permitted and enables the
execution of arbitrary commands as the `www-data` user.
